I thought that the movie and book were very similar in my mind. There were numerous therapists, nurses, and others coming and going. Morrie was receiving a lot of phone calls now also. In the movie i thought that Morrie was a little bit different personality wise. He listed everything off, and sort of went through everything less "personally" and didn't seem as warm. Maybe that was just the way i perceived him, or maybe the bad acting? :)
In the movie they discuss Mitch's girlfriend a lot more than in the book also.
In the video interview at first i thought that morrie looked a lot less frail than i pictured him. However once i saw his legs i realized that morrie was in fact veryyyy frail after all.
